Title: Circuit arrangement for the digital correction of time base errors of a television signal using variable addressing of a memory
IPC: G11B5/027
Filed: 1978-02-20
Abstract: In a circuit arrangement for the digital correction of time base errors in a television signal this signal is converted into digital television signals with a certain clock frequency in an analog/digital converter, which signals are consecutively written into the individual addresses of a random access memory (RAM) with the same clock frequency and in the meantime are read from specific addresses of the memory with the same frequency. Which addresses are read depends on the magnitude and sign of the time base error, which is determined in a detection circuit from a comparison signal of the television signal and is converted into digital time base error signals which are quantized with a given time interval, which error signals are applied to an address signal which depending on the number of time intervals, which are defined by the clock frequency, in the time base error signals relative to the number of addresses of the memory controls the selection of the addresses to be read.

Title: Subscriber line/trunk circuit
IPC: H04B3/23
Filed: 1978-03-01
Abstract: A microprocessor controlled subscriber line circuit for interfacing analog telephone lines and trunks to a digital switching system is disclosed. All processing of incoming analog signals is accomplished by the line circuit, including the interface between the line and a digital switching matrix, measuring, monitoring, testing of the signals associated with the speech path. Additionally, the dc signal powering the carbon microphone on the handset is generated as well as ringing and other tones. Equalization and providing the two-wire to four-wire conversion with acceptable echo performance and minimized cross-office transmission loss are also accomplished. Analog-to-digital and digital-to-analog conversions are accomplished under microprocessor control as are the tone and power generation functions in a programmable power supply configuration utilizing pulse duration modulated feedback control in a programmable signal generator. The described subscriber circuit is particularly advantageous in that it is designed to maximize its implementation using solid state circuit techniques including large scale integration as opposed to conventional components and relays.

Patent ES-8301133-A1 (ES)
Title: Bar stock guiding device for use with automatic latches
IPC: B23B13/02
Filed: 1981-07-07
Abstract: A bar stock guiding device for use with automatic lathes comprises two cushions which have the shape of semicylindrical annuli. The cushions are applied against each other in a recess of a freely rotatable sleeve. This sleeve is located between the lathe and a tube of the guiding device which contains the bar of stock fed to the lathe. The sleeve normally rotates with the bar of stock, because the opening appearing between the cushions is adjusted with minimal small free play only to avoid whipping of the bar in the cushions and the propagation of vibrations to the stock bar part extending in the working area of the tools. When the pusher passes through the sleeve, it ejects the cushions out of the sleeve recess. Before this ejection occurs, a braking mechanism reduces the speed of rotation of the sleeve to a substantial extent.

The hull panels (44) are formed according to the intended hull profile and are located at an angle of 90-180' in a polar plane in which the normal hull moving direction is 90'. At the inner side of the hull body (41) the groove and tongue elements (54, 55) provide a rib-like pattern of projecting and reinforcing material portions (53, 55). The hull body may be built free supporting or may be formed with support frames (16), bulk heads or similar transverse means, and the hull panels may be provided extending round the entire hull body or the hull body may be divided into two hull portions which are connected by means of an outer joint plate, for instance a keel plate (47), a border plate (48) or a stem plate (51). All joints of the hull body are secured by a glue joint, especially using a glue having a high shearing strength.

Abstract: An adsorber for separating gas mixtures or for gas purification contains an adsorbent bed and fittings for feeding and discharging gases. Gas which is to be separated or to be purified and regenerating gas are alternately passed through the adsorbent bed. In the event of pressure fluctuations, the surface of the adsorbent bed is whirled up, and peaks and depressions form on the surface, so that different adsorption lengths result for the gas which is to be separated or purified. In order to overcome the resulting deterioration in the efficiency of the adsorber, a smoothing device which acts on the surface of the adsorbent bed is provided in the adsorber according to the invention this can be operated from the outside, so that the surface can be smoothed during operation without closing down the adsorber.
